Out of Pokemon you listed, 4 of them has access to priority which renders Dugtrio useless for the rest of the game after successfully KOed these Pokemon. Additionally, Focus Sash cannot work if Stealth Rock is on field, which makes hazard removal a necessity. It has a poor synergy with one of the best Rapid Spinners, Excadrill.

That said, the increasing popular meta of Chansey and Toxapex is a good benefit to Dugtrio. Ability to trap these Pokemon can set apart stall cores in addition to the offensive Pokemon you listed. It is still a one-time use Pokemon after all, though.

I may move it up to B- for its more solid niche than those in C+.
